Abstract
The invention discloses a turbine rotor rotation work platform. The platform comprises a thermal insulation support part, a rotational part and a power part. The platform is characterized in that the thermal insulation support part is seated on the floor. The rotational part and the power part are buried in the ground, wherein the top end of the rotational part is at the same elevation with the floor and a pedal. The platform has the following advantage: 1, changing the traditional rotational heating manner using manual spray gun, the rotor can rotate, and the heating point can be fixed to be static. 2, applying the novel thermal insulation structure to concentrate the heat to the thermal insulation cap, the heat is not transferred to the whole turbine, the danger of skin burn is non-existent. 3, applying stationary loading manner to replace the original mechanical suspension manner, the danger of fusing steel rope caused by heating the rotor can be avoided. 4, applying the bolts for the connection of the support part and the rotational part, the part replacement is convenient. 5, applying the roller for supporting, rotating and driving the structure, the bearing capacity exceeds the suspension manner. 6, the machine is semi-buried in the ground, the integral occupied space is reduced, and the manual heat treatment is convenient.
Description
Technical field
The present invention relates to for a kind of device heating impeller before the assembling of turbine rotor part.It is particularly well-suited to one kind
Turbine rotor rotary table.
Background technology
One of steam turbine is thermal power plant with nucleus equipment of nuclear power station, its primary structure be by huge main shaft with
Suit multi-layer impeller composition thereon, and intensive blade is mounted with every layer of impeller.But the production system in steam turbine
During making, how safe efficient, the accurate impeller heating mantle of volume and substantial amounts is attached on main shaft is but always one
The individual engineering technology problem thoroughly not solved.
In actual production, process is set with for turbine blade at this stage to remain unchanged using the completely manual production processing
Mode.Namely manually impeller set is attached on the crane in Factory Building first, then ground is hung through artificial operation by crane.So
Afterwards Heat artificially is carried out with spray gun below the impeller being lifted by crane by crane by the hand-held heating of workman, and workman is in heating process
Need not stop to move.After simplified summary just it is found that this mode of production employed in actual production at this stage have with
Lower shortcoming.
1. the workman needing pistol in heating process at the uniform velocity moves to ensure homogeneous heating, due to each below impeller
Plant various kinds artificial origin, this heating uniformity is generally unsatisfactory.2., as components of steam turbine, volume and weight is larger for impeller
（Generally up to several tons）.Accidentally lead to drop once lifting fixation during lifting heating, non-for the workman below impeller
Often dangerous, the generation of production accident can be aggravated.3. use traditional method due to needing to lift impeller in advance, be transferred from ground, manually
Heating, multiple steps of manually removing stage makeup and costume, not only time-consuming take a lot of work but also inefficiency.
If a kind of rotor rotation work comprising to load the functions such as fixing, stable rotation and uniform heating therefore can be researched and developed
Station, solves the engineering technology problem in the heating installation process of above turbine rotor, it will bring high-tech profit to enterprise
Profit.
